The device partitioning is such that not all the debug components are mapped to an always-on domain. Typically, the programmer wants the debug setup to be preserved along a debug session, including subsystem power cycling. When debug registers are memory mapped and not implemented within the emulation power domain, the application software must save the state of the debug registers before going to sleep and restore them upon wakeup.
